I am using 2008 LT on a Sony Vaio laptop, with Vista Ultimate x64. Autocad runs fine, and Buzzsaw also......but I can not view any dwg drawings in Trueview. Each time I open to View a dwg, I get a "you must install window with a 203.3 mb file. I have used 2009, then went to 2010, then loaded design review, then removed and reinstalled all of them including Buzzsaw about 5 times each. I wrote tech support about 6 mo ago and they said that Trueview is not supported on an x64 machine.....and never will be. When 2010 came out, I thought it was my lucky day, but that has proven to be wrong. Any help would be appreciated. I download the files to my desktop and I can see fine in CAD....
